Answer:

5 between Martin's place and the school

Step-by-step explanation:

I don't know if you can draw a diagram from by directions, but you can try. It will help you to see the problem.

Draw

Draw a line that looks like this on your paper.

<===============:

school         X        Martin's place

Now draw a line going upwards from the arrow head.

∧                 Haley's place.

|

|

|

|

|

|

<=============:

school       x      Martin's place

Label the distance from the school to Haley's place as 12

I can't draw a line between martin's place and Haley's but you can. Label it as 13

So the givens are

c = distance between Haley's place and Martin's = 13

b= distance from the school to Haley's is 12

a = ? Distance from Martin't and the school = x

Formula

c^2 = a^2 + b^2

Solution

13^2 = 12^2 + a^2

169 = 144 + a^2          Subtract 144 from both sides.

169 - 144 = 144 - 144 + a^2

25 = a^2

sqrt(25) = sqrt(a^2)

a = 5              

The distance from Martin's place to the school (a) is 5 units, determined using the Pythagorean theorem with given values of 12 units from the school to Haley's place (b) and 13 units between Haley's and Martin's places (c).

Distance from the school to Haley's place (b): 12

Distance between Haley's place and Martin's place (c): 13

Using the Pythagorean theorem:

c^2 = a^2 + b^2

Substitute the given values:

13^2 = a^2 + 12^2

Simplify the equation:

169 = a^2 + 144

Subtract 144 from both sides:

25 = a^2

Take the square root of both sides:

a = √25

Simplify:

a = 5

Therefore, the distance from Martin's place to the school (a) is 5 units.

Answer:

$962.82 will be in John's account after 8 years if compounded semiannually.

Step-by-step explanation:

The formula used to find the amount after 8 years is:

A = P(1+ r/n)^nt

Where A = future value

P= principal value

r = interest rate ( in decimals)

n = no of times interest is compounded

t = time

Putting the values:

P = $600

r = 6% = 0.06

n = 2

t = 8

A= 600 *(1+0.06/2) ^2(8)

A= 600 *(1.03) ^16

A =600*1.605

A = 962.82

So, $962.82 will be in John's account after 8 years if compounded semiannually.

Answer:

105 square cm.

Step-by-step explanation:

The surface area of a square pyramid is

[tex]SA=A_{base}+4A_{lateral \ side}.[/tex]

1. The base is the square with side length of 5 cm, thus

[tex]A_{base}=5\cdot 5=25\ cm^2.[/tex]

2. The lateral side is the triangle with the base of 5 cm and the height of 8 cm. Thus,

[tex]A_{lateral \ side}=\dfrac{1}{2}\cdot \text{base}\cdot \text{height}=\dfrac{1}{2}\cdot 5\cdot 8=20\ cm^2.[/tex]

Now, the surface area of the pyramid is

[tex]SA=25+4\cdot 20=105\ cm^2.[/tex]

Answer:

The surface area of a square pyramid is: 105 cm^2

Step-by-step explanation:

The surface area of a pyramid is given by the following formula

[tex]A = l ^ 2 + 4 * (0.5) lh[/tex]

Where

l is the length of one of the sides of the square base

h is the height of the pyramid

We know that h = 8 cm and l = 5 cm

[tex]A = 5 ^ 2 + 4 * (0.5) * 5 * 8\\\\A = 25 + 2 * (40)\\\\A = 105\ cm ^ 2[/tex]

Step-by-step explanation:

A. you: Number of sandwiches = .5 * time

friend: # of sandwiched = .5 * t + 5

B. Your friend makes 10 and you make 5

The equations y1=x/2 and y2=(x+10)/2 model the sandwich-making process, where y1 and y2 are the number of sandwiches you and your friend make respectively. In 20 minutes, you can make 10 sandwiches and your friend can make 15 sandwiches. The graphs of these equations are lines with the same slope, indicating the same rate of sandwich-making but different start times.

Let's define the variables first. Let's say x stands for time in minutes, and y1 and y2 stand for the number of sandwiches you and your friend make, respectively.

a) The equations modeling the number of sandwiches made as a function of time would be y1 = x/2 for you (since you make one sandwich in 2 minutes) and y2 = (x+10)/2 for your friend (since your friend starts 10 minutes earlier than you).

b) If x is 20 minutes: for you, replacing x in the equation y1 = x/2, we get the number of sandwiches you make (y1) is 20/2 = 10 sandwiches. For your friend, replacing x in the equation y2 = (x+10)/2, we get the number of sandwiches your friend makes (y2) is (20+10)/2 = 15 sandwiches.

c) In comparison, the graphs of the two equations are lines with the same slope (0.5), indicating the same sandwich-making rate. However, they have different y-intercepts, signifying that your friend started earlier and therefore made more sandwiches.

Answer:

Final answer is x=23.

Step-by-step explanation:

Given that m∠A = 60°, m∠B = (3x − 2)°, m∠C = (2x + 7)°

We know that sum of all three angles of a triangle equals 180 degree.

So we can write equation:

m∠A + m∠B + m∠C = 180°

60° +(3x − 2)° + (2x + 7)°  = 180°

60 +3x − 2 + 2x + 7  = 180

67 +5x − 2  = 180

65 +5x  = 180

5x  = 180 - 65

5x  = 115

[tex]x=\frac{115}{5}[/tex]

x=23

Answer:

(x^5 - y)(x^5 + y)

Step-by-step explanation:

Step 1: Order the numbers from least to greatest

112, 130, 142, 150, 178, 206

The two middle numbers are 142 and 150.

The number between 142 and 150 is 146.

The median weight is 146 pounds.

The median weight of the wrestlers is 146 pounds.

To find the median weight, we need to arrange the weights in ascending order and identify the middle value(s).

Arrange the weights in ascending order:

112, 130, 142, 150, 178, 206

Since there is an even number of weights (6), the median is the average of the 3rd and 4th weights.

The 3rd weight is 142, and the 4th weight is 150.

Calculate the median:

(142 + 150) / 2 = 292 / 2 = 146

Step-by-step explanation:

It is given an expression,

(4a^2 - 3b^2)(16a^4 + 12a^2b^2 + 9b^4)

To find the correct answer

(4a^2 - 3b^2)(16a^4 + 12a^2b^2 + 9b^4)  can be written as,

(4a^2 - 3b^2)(16a^4 + 12a^2b^2 + 9b^4) = 4a^2 * (16a^4 + 12a^2b^2 + 9b^4) - 3b^2(16a^4 + 12a^2b^2 + 9b^4)

 = 64a^6 + 48a^4b^2 + 36a^2b^4 - 48a^4b^2 - 36a^2b^4 - 27b^4

 =  64a^6  - 27b^4 + 48a^4b^2 - 48a^4b^2 + 36a^2b^4 - 36a^2b^4

 = 64a^6 - 27b^4

Answer:

51.34

Step-by-step explanation:

First, things first, identify the opposite, adjacent, and hypotenuse.

Since you are trying to find the value of x, the length measuring 4 is the adjacent because it is one of the lengths that creates that angle measure you are trying to find. 5 is the opposite because the angle is on the opposite side of the length. The [tex]\sqrt{41}[/tex] is the hypotenuse.

Now, which trig equation do you want to use?

sin(x) = opposite / hypotenuse

cos(x) = adjacent / hypotenuse

tan(x) = opposite / adjacent

Let's first try solving with sine.

sin(x) = 5/[tex]\sqrt{41}[/tex]

Since you want to find the angle, you have to use the [tex]sin^{-1} (\frac{5}{\sqrt{41}} )=x[/tex]

Plug it into your calculator, then you should get something like this: 51.34019175.

That is the angle measurement of x.

Let's use cosine.

cos(x) = 4/[tex]\sqrt{41}[/tex]

Again, since you want to find the angle, you have to use the [tex]cos^{-1} (\frac{4}{\sqrt{41}} )=x[/tex]

Plug it into your calculator, then you should get something like this: 51.34019175.

You realize that it gave the same answer, right? Yep, let's also do tangent.

tan(x) = 5/4

Again, since you want to find the angle, you have to use the [tex]tan^{-1}(\frac{5}{4}} )=x[/tex]

Type it into the calculator and you should get 51.34019175 again!

Answer:

Bedroom Window: 1 1/3 feet wide

2 5/6 - 1 1/3 = 2 5/6 - 1 2/6 = 1 3/6 = 1 1/2

The width of the window of the living room is 2.125 times the width of the window of the bedroom.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

Emily's living room window is 2 ⁵/₆ feet wide the window in her bedroom is 1 ¹/₃ foot wide.

Convert the mixed fraction into a fraction number, then we have

2 ⁵/₆ = 17 / 6

1 ¹/₃ = 4 / 3

The ratio of the width of the window of the living room to the window of the bedroom is calculated as,

⇒ (17/6) / (4/3)

⇒ (17/6) x (3/4)

⇒ 17/8

⇒ 2.125

The width of the window of the living room is 2.125 times the width of the window of the bedroom.
